Answer:
C. Verbal
Explanation:
When you are trying to understand irony, the very essence of it is that something happens which is unexpected. Or something happens which is the opposite of the usual, intended meaning.
This story is about some guy who wants to take his kids to the circus. We know that this guy has a bad job and just BARELY manages to get by... he doesnt get paid well...
So do you know what sarcasm is? It's when people say stuff in a mocking way, where what they say isnt what they ACTUALLY MEAN. When this guy hears about this vendor asking for ELEVEN DOLLARS for a cup of lemonade... That's kind of messed up. But notice that this isnt specifically what creates the irony.
It's what comes out of Lawrence's mouth. "Oh, really? Just eleven dollars? That's totally worth it!" That's not what he actually means. He's being sarcastic with his words. He's using verbal irony.
